Referring to the accompanying drawings in which like numerals refer tolike parts throughout the several views. I have shown the coolingvapparatus in association with a heater device oi the character shownVin my aforesaid co-pe'ndw ing application Serial No. 726,346, died May18, 1934i, and which includes a. lower heater plate it and spaced heaterside plates il. The wrapped articles are moved along the plate labetween plates 2i by the succeeding articles during which 20 time thecontacting portions oi the overlapping wrapper material are heated andsealed through, the heat created by the plates 2l and il. The wrappedarticle then moves from between plates li to the cooling apparatus ofthe present invern' 25 tion, wherein thereis provided a metallic meansfor' rapidly cooling the overlapping portions oi Vthe sealed folds cithe wrapping material, which includes the circulation oi' refrigerantadjacent the portions that contact with the sealed iolds, 30

and which permits the use oi' relatively low," temperatures for quicklychilling the heated' waxed surfaces oi the folds of the wrapper.

` pulleys 2t which are mounted on shaits il jour- 40 nailed insupporting members 2t. The rearmost shaft 28 is driven by means oi asprocket 2l through the medium oi' achain beit it from a suitable sourceoi power. It is to be. noted here that the bottom heater plate il@entends up 45 to the rearmost ends oi the belts 22 (Figs. 1 and l1) andis disposed a slight distance below the plane oi the conveying side oibelts il. Each oi the vertical side belts 2l is spaced slightly abovethe belts 22 and operates from vertical pulleys 2s 50 which are arrangedin such a manner that the side belts 23 are oilset rearwardly oithe'bottom belts 22, as indicated in Pig. 1l, so that the side `belts 23extend over the heater bottom plate 2l.

The side conveyormeans 23 are movable to- 55 ward and away from eachother to compensate for different lengths of articles being wrapped, andin order to provide this movement a horizontal support 30 is provided ateach side of the mechanism. This support is provided wth front and reardepending members 3| and 32, respectively, the front member having aninternally threaded bracket 33'and the rear member 32 having aninternally threaded bracket 34. The brack-` ets 33 of the two forwardsupports 39 are carried by the oppositely threaded ends of a screw '35.Similarly, the brackets 34 are carried by the oplpositely threaded endsof a screw 36. The screws 35 and 36 are provided with sprockets 31 whichcarry a connecting drive chain 38 and screw 36 is provided with a handwheel 39. By rotating the hand wheel 39 the supports 30 can, therefore,be moved relatively to each other to adjust the relative positions ofthe side conveyor means or belts 23 so that wrapped articles of diierentlength may be accommodated. y l

The rearward pulley 29 for each side belt is keyed to a vertical shaft40 which is journalled in the support 30 and bracket 34. The forwardpulley 29 for each side plate is rotatably mounted on a spindlesupporting arm 4| which is plvoted to a bracket 42, a set screw 43 beingprovided in the bracket 42 for adjusting the position of arm 4 I. Thebracket 42 carries a rigid member 44 having screw threads 45 thereon,which member extends through a support 46 carried by the supportingmember 30, nuts 41 being threaded on the screw threads 45 at oppositesides of the support 46 so as to provide for longitudinal movement ofthe member 44 whereby the proper tension of the` side belt 23 can beobtained. J

The vertical shafts 40 of the rear pulleys 29 are each provided at theirlower ends with a bevel gear 48 which meshes with a similar gear 49mounted on a` shaft 50 carried by the bracket 34 (Figs. 7 and 9). Theshaft 50 has a pinion 5| which meshes with a relatively wide gear 52rigidlysecured to a shaft 53 which is journalled in the members 26. Theshaft 53 carries a pinion 54 which meshes with a gear 55 rigidly securedto the rear shaft 25, thus providing means for simultaneously drivingthe bottom and side conveyor means 22 and 23, respectively.

The side conveyor means or belts 23 are arranged to have substantialsliding contact with chambered heat absorbing elements 56 carried bybrackets 56a mounted on the supports 30 (Figs. '1

and 8) and similarly the bottom conveyor means or belts 22 are arrangedto have substantial sliding contact with a chambered heat absorbingelement 51 carried by the members 26 and which, in order to facilitateremoval of the bottom belts, may be comprised of two separate chambers(a) .and (b) (Figs. 6 and l0). Each element 56, as shown in Fig. 10, isprovided with an inlet and an outlet 58 and 59, respectively, and thechambers (a) and a compressor 64 and condenser 65l diagrammaticallyshown in Fig. 10, the condenser 65 being connected by a high pressureconduit 66 with the inlets 60 of the bottom heat absorbing elements 51aand 51h. The refrigerant is' returned through conduit 61, which is incommunication with the outlets 59 of the side heat absorbing elements56, to the suction or low pressure side bof the compressor 64.

the attainment of efficient, long lasting seals.

As there may be some tendency for the ends and bottom of the wrapper tostick to the chilling belts 22 and 23, I have provided at the endsthereof (Figs. 1 and 11) metallic side and bottom scrapers 68 and 69which have thin edges, respectively, in substantial engagement'with thechilling and heat exchanging conveyor means o r belts 23 and 22. 'I'hesescrapers 68 and 69 provide an emcient means for breaking the wrapperaway from the belts and also for removing any wax that may haveaccumulated on the chilling belts 22 and 23.

Suitable housings 10 may be provided for enclosing the side coolingdevices 56 and the upper edges of the belts 23, and these housings maybe lsupported on the supporting elements 3| and 32, as shown in Figs. 3,4, 5 and 8.

By arranging the side chilling and heat exchanging conveyor means orbelts 23 so that they engage the wrapped article ahead of the lowerchilling and heat exchanging conveyor means or belts 22 and by'havingthe upper sides of the belts 22 slightly above the plane of the bottomheater plate 20, it will be observed that a slightly curved surface willbe presented to the advancing articles as illustrated in Fig. 11, whichwill insure that the overlapping bottom folds will be engaged by thebottom chilling and heat exchanging conveyor means or belt 22 andproperly chilled. This is particularly advantageous in the case wherethe bottom of the article, such as bread, is dished, as the overlappingbottom portions of the wrapper will be fully engaged by the bottom beltsas they are moved onto the same to press the overlapped wrapper portionsfirmly against each other. Also, as'the wrapped article is iirst engagedby the side belts, the side 'edges of the article, in the case ofwrapped bread, will be slightly compressed as the article is carriedVonto the bottom chilling and heat exchanging conveyor means or belts,thus insuring a substantial contact of the bottom of the wrapped articlewith the bottom chilling and heat exchanging conveyor means or belt 22.

In the operation of the cooling apparatus described, the same isoperated at relatively low temperatures, such as below freezing, so thatthe heat absorbing devices which contact the horizontal and verticalbelts may become coated with ice, in which case the belts operate overthe iced surface and provide for a very rapid exchange- 'of heat,whereby the adhesive or molten wax between the sealed portion of thewrapper are very rapidly congealed.

In some instances it may be desired to remove the bottom or horizontalbelts and allow the bottom of the wrapped article to contact directlywith the horizontal heat exchanging members 51, and in the constructionshown in Figs. 12 to 14 the apparatus' is for the most part the same asshown in Figs. 1 to 11 with the exception that the horizontal or bottombelts have been omit- 75 I bottom plate 20 vof-the heater, are broughtinto engagement with the side belts 23 which carry the articles alongthe heater plate for some distance.'and Vto aligned drums |00 mountedonl a rotatable shaft |0i. The shaft |0| may be driven in the samemanner as the shaft 25 shown in Fig. l 1, and also may drive through thegearing prev viously described, the side belts 23. The plane of theheater plate is below the top surface of n the drums |00V so that thearticle is caused to travel over a curved surface in order thatin casethe bottom ofthe article isl dished, the over- 20 lapping portions ofthe wrapper at the bottom of the article will be pressed into ilrmengagement with each other against thebottom of the article. The sidebelts 23 'then carry the, article to the horizontal portion of the'cooling device which 25 comprises a pair of chambered heat absorbingdevices |02 through which the refrigerant is circulated, and then carrythe -article to a horizontaltable portion |03 which is adjacent themembers |02. The lower heat absorbing devices |02 and iml the verticalheat absorbing devices |04 over which the side belts 28 operate, providemeans for the circulation of the refrigerant, the same las the members00 and 01 of Figs. 7 and 8, and are connected to a refrigerantcompressor and other mechanism in any suitable manner such for exampleas the arrangement diagrammatically illustrated in Figlio.

By utilizing a device of the character described, relatively lowtemperatures may be had to rapid '40 ly chill yand ,OOn'geal theadhesive between the overlapping portions 'of the wrapper, which arebrought into contact with the cold side belts 23. and bottom belts 22 inthe case of the construction shown in Figs. l to 8, or the heatabsorbing devices |02 inthe case of the construction shown in Figs. 12to i4.

The cooling apparatus may be adjusted so that the same may be operatedand provide for below freezing or below zero temperatures if desired. so

5o that the chambered members or heat absorbing devices may becomecoated with ice, in which event'the wrapper portions at the bottom ofthe article will, if the construction shown in Figs. i3 to 14 isemployed, becausedto move along and-in contact with an iced surface,which will cause the adhesive to vcongeal very rapidly.

The heat absorbing devicesV |02 are provided with internal lbanles |00for causing the refrigerant to followa predetermined path tnere-.

6o through in order to uniformly maintain the surface thereof at thedesired temperature. The vertical cooling devices |04 may also beformed" with similar haines |00. Also. the sides of the heat 'absorbingdevices |04 opposite the article or g5 belt engaging sides thereof maybe insulated with any suitable insulation material |01 toincrease theectiveness of the sides thereof which ensage the article or the movablebelts. j

A cooling apparatus of the character described 70 provides ajmeans forrapidly congeaiing the heated wrapper material to provide for anefwrapped articles of variousfsises 'and is particube compressed.

Y portions of a wrapped article comprising horizon- 3 wrappers. althoughit is also adaptable for use with other wrapped articles.

Furthermore, it is to be understoodthat theV particular form o'fapparatus shown and de'- scribed, andthe particular procedure'setlforth,
